| Description : |
This gene encodes the rate-limiting enzyme in the de novo guanine nucleotide biosynthesis. It is thus involved in maintaining cellular guanine deoxy- and ribonucleotide pools needed for DNA and RNA synthesis. The encoded protein catalyzes the NAD-dependent oxidation of inosine-5'-monophosphate into xanthine-5'-monophosphate, which is then converted into guanosine-5'-monophosphate. This gene is up-regulated in some neoplasms, suggesting it may play a role in malignant transformation. |
| Bio-activity : |
Measured by its ability to convert the substrate inosine 5' phosphate (IMP) to xanthosine 5' phosphate (XMP). The specific activity is 136 pmol/min/μg as measured under the described conditions. |
| Molecular Mass : |
The protein has a calculated MW of 57 kDa. |
